Hrules and Column/Page breaks

[Jambunathan K <kjambunathan@gmail.com>]

Is it possible to extend horizontal ruler to also stand for page *and*
column breaks (say) by attaching a header to it. For it to be useful,
the page break can have a style attached to it that specifies what
manner of pages that this break introduces. 

(For example, start emitting Frontmatter pages from here on. Start
emitting Regular pages from here on.)

Would you be interested in formalizing this arrangement? WDYT.

Org file below:

--8<---------------cut here---------------start------------->8---
* Headline

There is horizontal line below.

#+header: some qualifiers
------------------

There is a horizontal ruler above.
--8<---------------cut here---------------end--------------->8---


gets transformed to this:

#+begin_src emacs-lisp
(headline
	   (:raw-value "Headline" :title
		       ("Headline")
		       :begin 403 :end 531 :pre-blank 1 :hiddenp nil :contents-begin 415 :contents-end 530 :level 1 :priority nil :tags nil :todo-keyword nil :todo-type nil :scheduled nil :deadline nil :timestamp nil :clock nil :post-blank 1 :footnote-section-p nil :archivedp nil :commentedp nil :quotedp nil :category nil)
	   (section
	    (:begin 415 :end 530 :contents-begin 415 :contents-end 530 :post-blank 0)
	    (paragraph
	     (:begin 415 :end 449 :contents-begin 415 :contents-end 447 :post-blank 1)
	     "There is horizontal ruler below.")
	    (horizontal-rule
	     (:begin 449 :end 495 :post-blank 1 :header
		     ("some qualifiers")))
	    (paragraph
	     (:begin 495 :end 530 :contents-begin 495 :contents-end 529 :post-blank 0)
	     "There is a horizontal ruler above.")))
